 widget-&gt;private
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For dspless mode, we need to allocate and store an 'sdai'
structure. The existing code allocate the data on the stack and does
not set the widget-&gt;private pointer.

This minor change should not have any impact on existing DAIs, even
when the DSP is used.
